Stages of Cervical Cancer

There are 5 stages and 12 substages of cervical cancer:

Stage 0 (Carcinoma in situ): In this stage, the cancerous cells are present only on the surface of the cervix.

Stage I: In this stage, the cancerous cells invaded deeply into the cervix tissue, but the cancer is confined to the cervix.

  • Stage IA: The cancer can be identified only under microscopic examination. This stage is divided into two substages according to the tumor size.

    • Stage IA1: The cancer is less that 3 millimeters deep into the cervix tissue and only 7 millimeters wide.

    • Stage IA2: The cancer has invaded an area less than 7 millimeters wide and is between 3 and 5 millimeters deep.

  • Stage IB: In this stage, the cancer can be seen without a microscope and has invaded the connective tissue of the cervix. The cancer is deeper than 5 millimeters. This stage is also subdivided into two substages according to the tumor size.

- Stage IB1: The cancer is less than 4 centimeters large.

- Stage IB2: The cancer is more than 4 centimeters large.

Stage II: In this stage, the cancer has spread to adjacent tissues, but is still confined to the pelvic area. This stage is divided into two substages according to the cancer's extent.

  • Stage IIA: The cancer has spread to the upper part of the vagina, but the lower part of the vagina is not affected.

  • Stage IIB: The cancer has spread to the tissue near the cervix called parametrical tissue.

Stage III: In this stage, the cancer has spread to the lower part of the vagina and also to the pelvic walls. This stage is divided into two substages according to the cancer extent (how far the cancer has spread).

  • Stage IIIA: The cancer has spread to the lower part of the vagina and is confined in this area.

  • Stage IIIB: The cancer has spread to the pelvic walls and can block the urine flow to the bladder.

Stage IV: In this stage, the cancer has spread to other parts of the body. This stage is divided into two substages according to the cancer location.

  • Stage IVA: The cancer has spread to the bladder or rectum.

  • Stage IVB: The cancer has spread to distal organs (organs located far away from the origin) within the body.
